AIM To explore the in-depth application of interactive digital teaching model in the theory teaching of internal medicine circulatory system.

METHODS Sixty undergraduate students majoring in clinical medicine of our university were included as the research subjects and they were divided into two groups by random grouping. The theory study effect of the two groups was evaluated by examination and investigation. The experimental group (n=30) adopted the interactive digital teaching mode for practical teaching of circulatory system diseases and the control group (n=30) applied the traditional teaching mode. After the theory teaching in the two groups, examination of situational simulation case analysis was conducted and the students' effect evaluation of the teaching model was surveyed by questionnaires. SPSS 26.0 was used for statistical analysis.

RESULTS The test scores of the experimental group were significantly higher than those of the control group and the questionnaire scores of the teaching model were higher than those of the control group, with statistical significance (P<0.05). The experimental group had better feedback on interactive digital teaching mode compared with the feedback on the traditional teaching mode of the control group.

CONCLUSION The application of interactive digital teaching mode significantly improves students’ classroom concentration and knowledge mastery, which is suitable for the practical teaching of internal medicine circulatory system.
